This invention relates to the art of folding and wrapping paperarticles. A primary object of the invention is to provide a mechanicalcombination which will perform one or more folding operations from aninitial blank flat piece of paper in such a manner that the folds willbe definitely and uniformly located in all of the folded papers andfurthermore to have those folds creased down tightly so as to preventbowing of the paper between adjacent folds.

A further primary object of the invention is to provide a mechanicaldevice which will apply a wrapper to the folded articles in such mannerthat the wrapper will always be properly aligned on each article andwill draw the folds thereof down snugly.

A still further primary object of the invention is to provide blankreceiving means which will initially accept the blanks and retain theblanks throughout all of the various folding and wrapping operations. .Astill further primary object of the invention is to provide such blankholding means in a manner that will carry the blank from one station toanother as the various operations are performed on the blank, allwithout disturbing the alignment of the blank so as to preserve accuracyin those various operations.

I provide ar shelf 55, Figs. 1 and 2, between the legs of a tab-le 55and mount thereon a driving motor l, which, through a suitable belt 58,drives a pulley 59 xed to the shaft 5i? carried transversely acrossunder the table top 55. A smaller pulley 5i is Vfixed to the shaft 5l]and drives a belt 62 which passes up through an opening in the table topto drive the larger pulley 53 which is fixed to the transverse maindrive shaft 54 revolublycarried by the brackets 55 and 66.

Between the pulley 53 and the bracket 55, I x a spur gear Eil on theshaft 54 to mesh with a spur gear 58 iixed to the central shaft t9 whichis revolubly carried by the brackets 'l0 and ll. Revolubly mounted onthe shaft 69 is a disk l2 having a plurality of teeth, here shown as 18in number. Each tooth T3, Figs. 4 and 5, is separated from its adjacenttooth by a radial slot, and each tooth is further provided with an arcu--ate periphery. y

On the right hand end of the shaft il@ is fixed a disk lll which has acylindrical portion l5 in the path of the teeth'l of the properYdiameter to fit into the arcuate portion. of each tooth upon suitableturning of both disks i2 and le, as indicated in Fig. 5. On one side ofthe cylindrical portion l5, I Icut away a portion to leave an arcuateslot l5. On a radial Vcenter line of this slot and extended beyond thecircumferential line of the cylindrical portion l5 I x a pin il of theproper diameter to permit it to slidably enter into the slots betweenthe teeth I3. The two disks 'l2 and 'lll together with the cylindricalportion 'l5 and the post ll' form a Geneva stop. In operation, turningof the shaft 54, will cause the pin or post Ti to turn the disk l2 untilthe pin il leaves the slot, Fig. 5. The disk 'l2 will turn no further onaccount of the fact that the cylindrical portion le of the disk 'lll hasturned around into the arcuate outer face of the adiacent tooth 'i3 toprevent further travel of the disk l2, although the disk lill continuesto revolve as the shaft 54 turns. The next movement of the disk 'l2 willoccur Ywhen the pin 'il comes on around in a counter-clockwisedirection, Fig. 5, and enters into the next above slot in the disk l2.

The disk l2 has a plate l fixed thereto by means of a hub 19, Figs. 3and 4. The table top 55 is cut away to permit the disk l2 and theattached plate 'i8 to extend therethrough.

Spaced around the periphery of the plate l are a plurality ci blankcarriers generally designated by the numeral Sli, there being preferablythe same number of carriers as there are teeth i3 in the disk l2.Referring to Figs. 13-15, each carrier comprises a plate 8l fixed to theplate l and has an anvil 82 extending over the peripheral edge of theplate i8. Hinged tc the plate 8l is a finger 83, the free or open end ofthe ringer 83 being turned in that direction toward which the plate 'i8revolves. A spring El@ is xed by one end to the finger S3 and by theother end to the plate Bl to normally retain the finger 33 in closedposition against the anvil lli?. When the linger B3 is lifted to itsopen position, the heel 5 thereof strikes the peripheral edge oi theplate 'i3 so as to swing the longitudinal axis of the spring 51? aroundslightly to the rear of the axis of the hinge pin 86, therebyYpermitting the spring 85 to hold the nger 83 in that open position. Eachoi these fingers 8S is provided with a plurality of needles 8l, hereshown as two in number, te extend from the under face of the nger andenter holes in the anvil 82.

The article to be worked upon in one'particular instance comprises arectangular piece of 88, Fig. 45. A supply of these 33 is car riedbetween two horizontally disposed, vertically extending guides t9 and2li carried by the bracket 9i above the rear end of the table A .lorigintudinally slotted floor 92! provides the lower rest for the blanks 58.The blanks are aligned cross ways over the floor 52 between the sideguides to have each blank resting on its edge and maintained in verticalalignment one against the other. This alignment is preserved by means ora follower 53 which has a Vloot fitted in the slot of the floor 52. A.weight 95 by means of a cable or chain 5S passing up over a pulley 5lcarried by the bracket 9i and thence forwardly around a pulley Q8 andrearwardly back to and attached to the follower 94, serves to keep theThese pins S9 are adjustably caried bythe re`H taining Ylugs E55 so thatthe pins maybe posi- Y tioned to extend by any desired length over theforward blank Se.

As above indicated, the plate 'i8 is intermittently moved through theGeneva stop mechanism by the motor 5l and the plate 18 revolves in acounter-clockwise direction as viewed from the left hand side, Fig. l,or in that direction wherein the blank carriers 80 are moved from therear of the machine and around over toward the front. The normalpositions of each of the finge-rs 83 as they come from under the tabletop t up therethrough to appear thereabove at the rear of the plate i8are indicated, Fig. l, below the table top 55 wherein those fingers arelifted from their anvils to extend substantially radially from theperiphery' of the plate 68. In other words, the fingers yare in what istermed the open positions.

The mechanism is so arranged that in each successive stopped position ofthe plate 18, one of these fingers S3 will be positioned substantiallyhorizontally on the rear side of the plate i3 as indicated in Figs.8-10.

Now in order to carry a paper blank 88 from the supply and over againstthe anvil 82 to be subsequently gripped thereagainst by the nger 83, Iprovide a. head, generally designated by the numeral lei. This head hasa vertically disposed face |d2 with a plurality of perforations |63therethrough, here shown as being a series of holes in vertical rowstoward each end of the face with a few holes in the center thereof. Thisface is arranged to be of that size which will bear against the foremostblank 88 between the pins @il when the head is carried thereagainst.These holes it extend through from the face into the head into a chamberIll therein which is normally substantially evacuated through a passageQ5 leading therefrom down into the base of the head. A hose 5% connectswith the base to communicate with that passage |65 and is carried ondown to a vacuum pump |61 which is driven by the belt Hi8 from thepulley |05) fixed toy the shaft "Eil,

The head lill is supported through a base H which in turn is carried bya roller which runs in a slotted guide i l2 thereby not only supportingthe head but also guiding it and limiting it to reciprocating travellongitudinally of the table In order to reciprocate the head lill, Iprovide a mechanism Which will now be described. A shaft H3 is mountedtransversely of and above the table 5ft to be carried by bearings in thebr-ackets Mil and l l5, Fig. 18. The shaft is driven by the gear lltwhich meshes with the gear G3, Fig. l., Fig. 3. On the inner end of theshaft H3 is fixed a disk il. to have a pin H8 extending inwardlytherefrom near its outer edge. A

- connecting rod is pivotally connected to the pin H3 by one end and iscarried rearwardly to have its rear end connected pivotally to a lever|2|lv which is rockably mounted on a transverse shaft 22|. Another lever|22 is fixed rigidly on the shaft |2| to entend upwardly alongside thelever i2@ and is provided with an arcuate slot in its upper end throughwhich a screw |23 slidably passes to screwthreadedly engage the lever|23, thereby adjustably securing together the two levers |26 and |22.

The rear end of the connecting rod H9 is slotted, Fig. 19, so that therod ||9 may travel in either direction as the case may be with aninitial motion before shifting the lever.

The shaft |2| extends across the rear end of the table top 56 to have anend thereof engaged by the hub |24, Fig. l0, of a lever |25. This lever|25 is turned upwardly to have its upper end pivotally engaged with anupturned ear on the rear end of the base HQ.

The lever |25 is on the right hand side of the base. On the left handside of the base liti, Fig. 16, is another lever |25 which has its upperend likewise pivotally connected to an upturned ear on the base lid andits lower end fixed to the shaft |2l.

Over the hub |24 is placed a shoe i2? which has a friction lining |28thereunder yieldingly carried against the hub by means of a compressionspring |23 forced against the shoe by a thumb screw |353 on the upperend of a stud |3| carried by the table top e6 and passing through theshoe.

New as the motor 5l' drives the train of gears 6l, E8, and H5, theconnecting rod H3 will reciprocate the lever |29 and in turn reciprocatethe shaft |2| to cause corresponding reciprocation of the head |il|. Thelevers |20 and |22 are relatively adjusted by means of the screw |23 togive that travel whereby when the lever |23 is rocked to its rearmostposition, the face |32 of the head lill is brought up into compressivecontact with the foremost blank 8S, the weight Q5 permitting a yieldingcontact. In this position, the connecting rod H9 has traveled to theforward end of the slot in the rear end thereof against the connectingpin in the lever |26. Therefore by reason of the slotted end, there willbe a delay in the forward movement of the head |95 through r'ontinuedrevolving of the shaft i3. The head will be moved, however, by the timethe connecting rod ||9 is pulled forwardly suilciently to have the rear.end of its slotted connection brought into Contact with the connectingpin on the lever |20 so that the head itl will then be carried from theposition shown in Fig. 9 and also the dash line position shown in Fig.forwardly to the solid position shown in Fig. 10, the position in Fig. 9being that just before the head im has reached its rear limit of travel,the dash line position in Fig. l0 being the rearmost position.

Since there is a high degree of Vacuum in the chamber la@ in the headim, air will be rushing in through the face m2 through the holes |03. Byreason of this condition, when head iti starts travelling forwardly, asingle blank lll will be across the face |92 and the vacuum will holdthe blank in that position so that as the head moves forwardly, the endsof the blank will be slipped from under the pins 99 and the blank willbe retained on the face as the head travels.

A pair of fingers |32 and |33 are mounted in parallel relation, one on aplate i3d carried in spaced parallel relation to the plate I8 and theother finger, linger |33, on the plate adjacent the plate 18, Fig. 8.The upper edges of these fingers |32 and |33 are located in thatelevation such that when the blank 8S is carried forwardly it will. becarried up over these fingers with the ends of the blank extendingbeyond the respective fingers. Thus one end, the left end, of the blank83 will be carried over the iinger d3 against the anvil 82. Immediatelythe head l reaches that po.. i Where the blank 3d has come into contactwith the anvil 82, the ringer 33 is kicked upwardly to come around andgrip that end of the blank S23.

This movement of the nger 25 is accomplished by means of the followingmechanism. A

L 7 tile cam |35 is properly fixed to the shaft H3, Fig. 19, and an arm|35 is rockably mounted by its forward end on a bracket lt? to extendover and above the cam |35 to have a depending foot |53 in the path ofthe cam with a roller |39 resting on the cam. A spring it@ normallyholds the arm |35 in its lower position. A connecting link Mi extendsdownwardly from the rear end of the arm |35 to rockably engage a lever|42 which is fixed on a shaft M3 extending transversely across the tabletop between the bearings iil and H215, Fig. i8. A spur gear |45 is fixedto the shaft |43 and meshes with a smaller gear lfil thereabove which inturn is xed to a shaft extending through the upper end of the bearing 45to carry the crank arm |48 which in turn has a projecting pin liti). Asthe cam |35 lifts the arm i365, the crank arm M8 is given a rapidmovement to swing around, Fig. 10, to carry the pin lll up under thefinger 83 a sufficient distance to permit the spring 85- to flip thefinger on around to the closed position as indicated by the dash lin-es.As this finger 83 snaps into the closed position, the needles 8lpuncture the blank 88 so that the blank is then held in a fixed positionas indicated in Fig. l4.

Immediately the finger 53 is in its closed position, the head iili hastraveled forwardly sufficiently to have the forward end of the plungerrod |55 strike a stop |5|, Fig. i0. This plunger rod |55 slidablyextends into the head |5| to carry a piston valve |52 thereon within thechamber |55. Normally, a spring |53` around the projecting end of therod |55 retains the rod in the extended position whereby the pistonvalve |52 is in the forward end of the chamber |04 as indicated in Fig.9, but when the rod has been stopped by the stop 55| as in Fig. l0, thehead lili continues to move forward thereby giving the relative effectof the valve |52 moving rearwardly in the chamber iiitoward the passagesleading to the holes |53 and to uncover in part the passage |65. One ormore passages |54 lead from the chamber ltd through the rear side of rthe head iti to discharge therefrom, the valve |52 in its normalposition closing off these passages but in the rearmost position as inFig. 10, leaves these passageways open thereby destroying the vacuumwithin the chamber lfii to some extent behind the valve |52. Thereforeby the time the head itl reaches its foremost limit of travel, thevacuum which has retained the blank S against the face has beendestroyed insofar as any holding effect of the blank 88 is concerned.Now due to the slottedr arrangement of the connection between the rodIl@ and its lever itil, the head lii will again be allowed to remain inthat forward position for a period of time before it is again carriedrearwardly to repeats its operation.

While the head iii is thus retained in the forward position, the platei5 is advanced by the Geneva stop mechanism to carry the blank on up andaway from the head. In this upward travel, the blank S8 which extendsfrom the retainer Sii passes upwardly under a guide |55 and comes torest at its first folding position. At this location, a foldingmechanism, generally designated by the numeral |55 is mounted by beingattached to the inside of the right hand plate ift-ift. The blanket isbrought around over an anvil i5? and under a plate |53, Fig. 22,whereupon a Iblock |59 normally carried below the blank so kas to permitthe blank to pass thereover. is pushed upwardly and rocked around VVlythat of the rst folder |576. Vto the backV Iltis a slide |79 by means ofthe aces/,51e

and over the plate |58 so as to push that portion of the blank 88extending beyond the plate |58 upwardly, around and over and down ontotop of the plate. Immediately upon accomplishing this folding operation,the block |59 is revolved around and back and then pulled downwardly toits original position. The mechanism for operating the block |59 isindicated primarily in Figs. 20-24. A body |60 is secured to the innerside of the plate |34 and carries a slide i5! thereon normally pulled toa lower position by means of a spring |52. b-y means of side plates |53and |5i fixed to the body |60 to lap over in part tongues |55 and |55respectively of the slide, Figs. 20'and 23. The lower end of the slide|i| carries a roller |57 which rides on a cam |68 which is fixed to theshaft 59 and is positioned between the plates 'i3 and |34. As the cam|58 revolves with the shaft 69, it has a proper peripheral contour suchthat the slide |5| is lifted as soon as the blank 88 is brought up tothe position over the anvil |51 and is stopped. The slide |5| carries aspur gear |69, Fig. 24, which meshes with a rack il@ fixed on the body|55 between it and the slide. The gear on therside of the gear |5 inturn meshes with an upper gear |72 which is fixed on the spindle |13revolubly carried in the upper end of the slide ||i| to extendtherethrough and to carry the block |59 thereon. The gear |T|| is largerthan the gear |12 so as to give on increased speed to the spindle |13 ascompared to the spindle |14 which carries the gears |59 and As the cam|58 revolves, the slide is lifted and thereby causes the gears aboveindicated to revolve to initially lift' and simultaneously rock theblock |59 as above indicated and as shown by dash lines in Fig. 22. Theblock |59 is so formed as to have a semi-cylindrical heel with anextending rectangular portion, the cylindrical portion in effect beingrolled upwardly and around over the edge of the plate |58 to crease theblank 38 at the fold. The slide is then returned by the spring |52 uponcontinued travel of the cam |68 so as to bring the block |59 back downvout of the path of the next blank 53 to come thereover.

'Ilus first fold is that as indicated to be made along the dash line a,b, Fig. 45, and as completed in Fig. 46. In the form therein shown, theline a, b, is not at right angles to the edges of the blank, althoughthe fold may be made to be square by varying the slope of the edge ofthe plate |53 as desired. Y

Immediately upon completion of the folding operation as above describedand the return of the block |59 to its initial position, the plate 'i8is moved another step to carry that blank |35 on to the next foldingposition where the blank 88 again comes to a complete stop. It is to beremembered that throughout the Various operations described andhereinafter to follow, the blank 85 is rigidly gripped by the finger S3pressing the blank against the anvil thereunder. At this second foldingstation, there is a folding mechanism positioned which is generallydesignated by the numeral H5.

This second folding mechanism has a back |175 which is attached to thestationary plate |355 by the screws Vil and il, Fig. 25. The structureof this second folding mechanism resembles close- Slidably engaged Theslide is retained in position side plates |88 and I 8| The lower end ofthe slide Vl@ has a roller |32 in the path of the actuating cam |68which is the same cam that operates the first folding mechanism. Areturn spring |84 attached to the slide by one end and to the back |76through the side plate I 0| normally retains the slide in a loweredposition with the roller |82 in Contact with the periphery of the cam|68. The slide lid carries a spur gear |85 on a pin |86 to have the gear|66 mesh with a rack |82 secured to the back A larger spur gear |80 islikewise fixed on the pin or shaft 86 to revolve therewith and is meshedwith a smaller spur gear |86 carried on a second shaft |66 which passesthrough a part of the slide i256 as a bearing to extend outwardlytherefrom to receive in fixed position thereon the revolving foldingblock I6l.

The folding block lill is thus revolved upon travel of the slide H6 asit is reciprocated up and down by the cam |68 and the spring 581i.Referring to Fig. 25 in particular, the block |9i is normally turned tolie within a recess in the anvil |62 so as to permit the blank 88 tocome around and over and under a plate |63 immediately thereabove. Thisplate 93 is so located that its edge directed toward the plate |36terminates along a line on which the second fold is to be made, beingthat line in the present instance as indicated in Figs. l5 and 46 by theletters c, d, this line in this case being at right angles to the edgesof the blank. The blank 88 remains stationary when the slide V56 israised by the cam |68 to cause the folding block I9! to be lifted andsimultaneously revolved around and over toward the top side of the plate|93 thereby carrying the projecting portion of the blank 88 upwardly andaround and down into compressive contact with that top side of the plate|03, the travel being indicated by the dash lines in 25.

It is to be remembered that when the blank 80 has reached this secondfolder, the initial fold has already been made and in order to preventthe inner end of the blank from interfering with the second fold, Iprovide a finger 64 which is hinged by its upper end to a bracket |95secured on the top end of the back |76. A spring normally retains thisfinger in positions indicated in Figs. 25 and 27 which is that positionwherein the under edge of the finger initially is above the innermostend of the folded over end of the blank 88 so as to prevent that endfrom interfering with the second fold or actually sliding back thereoverwhen the second fold is being made. Thus when the folding block |85starts upwardly,

= the lower end of the nger |66 initially retains that free overturnedend of the blank 88 sunlciently long to permit the projecting end of theblank 88 to be turned upwardly while that free end is held against theunder portion of the blank being raised thereagainst, following which,the block ISH pushes the nger on back over the plate 93 as indicated inthe dash lines in Fig. 25 so as to permit the completion of the secondfold without further interference.

As soon as the cam E68 has been turned sufiiciently to permit the springI 82 to return the slide llt to its normal lower position, the plate I8is then moved to its next position and there stopped. By the time theblank reaches this third position, it has been folded to the form shownin Figs. 47 and 48. In this third position, a wrapper is applied.

A roll of paper 566 is revolubly mounted between a pair of plates i9?and |68, Fig. 3, which are supported by a standard l99 from the tabletop 56. This paper roll |96 is essentially a tape in rolled form, thewidth of the tape being substantially that of the distance between thetwo folds of the blank 88. The end of the tape is drawn from the roll|96 and laid over a roller 200, Fig. 40. An arm 20| is hinged betweenthe vertical plates 282 and 203 which hang from the horizontallydisposed plate 20G which in turn is secured to the vertical standard 205which extends upwardly from the table top 66, Figs. 2, and 6. On theforward end of the arm 20| is mounted a knurled roller 206 to come downon tcp of the tape |96 to grip the tape between it and the under roller200. A spring 20'! normally pulls the roller 206 against the tape. Inorder to thread the tape |65 between the rollers 200 and 208, the arm261| may be swung upwardly as indicated by the dash lines in Fig. 40 andthen allowed to return under the influence of the spring The shaft 20Bon which the roller 206 is mounted extends revolubly through the frontend of the arm 20| and has a spur gear 209 xed on its other end. Thisgear 209 is meshed with the gear 2li] when the arm is in its loweredposition and the gear 2 I 0 is on the shaft 2| I which extends throughthe plate 203 to carry another spur gear 2|2 on its outer end. A spurgear 2|3 meshes with this gear 2 I2. The gear 2|3 is given anintermittent motion by means of a ratchet wheel 2H! being mounted on thesame gear shaft and having a pawl 2|6 mounted on the upper end of alever 2| 6, Fig. 2, intermittently reciprocated across the top side ofthe wheel 2|4 by means of a cam 2|? fixed on the shaft 69 and rockingthe lever 2 i8 by contact with its lower end through a roller 2|9 and aconnecting link 220 between the arm 266 and the upper end of the lever2|8. A spring 22| causes the roller 2|9 to follow the periphery of thecam 2|I as it revolves.

Therefore in timed sequence as determined by the cam 2|? and theconstantly revolving shaft 69, the knurled roller 266 is caused torevolve to give a definite length of feed of the tape |96. The forwardend of the tape is fed up onto a table 222, Fig. 40. The feed of thetape is arranged so that for every feeding operation, there is a lengthof tape fed onto the table 222 of the desired length to be wrappedaround the blank 88. In order to transfer the desired length of tapefrom the table 222 to the blank 88, I employ in general a pneumatic headwhich lifts the tape length by means of a vacuum, carries the tapelength across a glue applying roller, and then presses it into positionon the blank 88. The mechanism for accomplishing this operation is nowto be described.

On a transverse bar 223 carried between the standard 205 and a standard224 extending vertically from the table top 66, I slidably mount a crosshead 225 so that it may be reciprocated transversely across themechanism thereunder. In order to accomplish lthis reciprocating travel,I fix a cam wheel 226 to the shaft 69 toward the left hand end thereof,Fig. 6. This cam wheel 226 has a groove cut around its periphery curvingfrom one side of the wheel to the other to receive a pin 221 thereinfrom the rocker 228 which is pivotally mounted on the table top 56. Iheupper end of the rocker 228 is attached through a slotted end to a rod229 which slidably passes through a boss 230 on the front side of thehead 225. This rod 229 is normally held in a central position by meansof springs 23| and 232 on either side of the boss 230. Now as the shaft69 revolves, the pin 22'I in following the groove in the periphery ofthe wheel 226 will cause the arm 228 to swing transversely and therebyreciprocate the head 225 accordingly. The springs 23| and 232 areemployed tov prevent jerking of the head as the travel thereof isreversed, the

springs forming a resilient connection between Y the rocker 228 and thehead.

,A hollow shaft 233, Fig. '7, is vertically guided through the rearportion of the head 223 to permit vertical reciprocation. The shaft 233is secured against vertical travel therethrough in a lifting head 234.This lifting head 234 is slotted transversely across its forward side toreceive thereacross and in the slot the bar 235, the lifting head 234being free to slide along the bar 235 as the head 225 is moved.

The upper end of the shaft 233 is counterbored to receive therein a tube236 and the upper end of this tube 236 is supported by a lifting head23'! which in turn is slidably secured on a transverse bar 23B.

The shaft 233 is provided with a port 2316 affording va discharge intothe atmosphere from the lowerk end of the counterbore. Also a passageway24B leads from near the upper end of the shaft counterbore out throughthe lifting head 234 to have a flexible hose 24| leading therefromaround down to a vacuum pump 242. This vacuum pump 242 is driven by thebelt |68, the belt driving bothrpumps Ill'l and 242. The tube 236 isclosed off at its upper end by the head 237 but has an opening 243 inits side adapted to register with the passage 240 when the tube is inits lower position. In this position the port 239 is closed.

A head 244 is attached to the lower end of the shaft 233110 have anunder face horizontally dis-Y posed with a plurality of orifices formingpassages leading back into the head to be in communication with thecentral passage in the shaft.

The transverse bar 223 is fixed in position but the transversebar 235 iscarried in the outer ends of arms 245 and 245, the rear ends of whichare rockably supported respectively by the standards 224 and 205.Springs 247 and 248 extend respectively from the arms 245 and 246 downyto the standards so that the bar 235 is nomnally urged to the lowerposition as indicated by the solid lines in Fig. 6. The lever 245 ismounted ona shaft 249, Fig. l, which extends through the standard 224and has a lever 25|] secured on its outer end. A connecting rod 25|pivotally connects with the rear end of the lever 25|) and extendsdownwardly to an arm 252, the rear end of which is pivotally supportedin a bracket 253 carried by the table top 56 and extends forwardlytherefrom over a cam 254 which is fixed on the shaft 64. A rollercarried by the arm 252 is pulled into rolling contact with the peripheryof the cam 254 and there yieldingly retained by means of a spring 255extending from the outerVY end of the Yarm down to the table top.

The transverse bar 238 is likewise carried between the rear ends of arms256 and 25| rockably supported by their forward ends by the standards224 and 205. The arm 256 is fixed o-nra shaft 251' which extends throughthe stande ard 224 and carries a lever 258 on its outer end and turnedrearwardly to have attached thereto arm is brought to bear against thecam 26| through a roller by means of a spring 262. attached to theforward end of the arm and also the table top S.

The operation of the feeding head will now be described. Assuming thatthe head 244 is in the solid line position as shown in Fig. 6 whereinYoperation has just been completed, rotation of the shaft 64 will causethe cam 26| to push upwardly on the connecting rod`259 to in turn liftthe head 23'5 suiciently to cause the lower end of the tube 236, Fig. 7,to be lifted above the port 239 so as to destroy the vacuum that mayexist within the shaft 233 and consequently at the head 244. Immediatelyfollowing this initial move, the cam 254 has come around in its cycle ofrotation and then lifts the connecting rod 25|, and consequently thehead 234 which pulls the vacuum head 244 upwardly toward the cross head225. The two cams 254 and 26| continue to hold the heads 231 and 234 inthe upper positions as indicated by the dash lines, Fig. 6, while thecam 225 pulls the rocker 228 over toward the right hand side of themachine so as to shift the cross head 225 over to the right as indicatedby the dash line position. As soon as this position is reached, the cams254 and 25| have revolved sufficiently to permit the heads 23T and 234to be lowered andconsequently bring the vacuum head 244 down toward thetable 264, Fig. 40. The

alignment is such that the head 244 will be lowered directly down ontothe end of the tape |96 which has previously been fedV onto the table asheretofore indicated.

When the head 244 has thus been lowered, the tube 226 has been loweredinto the shaft 233 also soy as to close off the port 239 and also tobring the opening 243 into registry with the passageway 245 in the head234 so as to permit an evacuation of the bore within the shaft 233 andconsequently the head 244. The result is that the length Y of tape 95then under the head is brought into intimate Contact with the under faceof the head and there retained as a closure to the orifices in thatface. However as the head 244 descends into position onto that length oftape, a hook 253 attached to the side of the head 244 strikes a knife264 which extends transversely across vthe tape |96 so that by the timethe head 244 has come into contact with the tape, that length of tapethereunder has been sheared by that knife Yand therefore the length thuscut off is free to be lifted by the head 244 under the influence of thevacuum. Y

The knife 264, Fig. 4l, is rockably supported by a screw 262 within aslot in the table 264 and has a spring 258 normally pulling down on therear end of the knife so as to rock the other end upwardly as indicated,the spring normally holding the knife in the open position by a stop269.

The contours of the cams 254 andr26| are so shaped that as soon as thehead 244 has picked up the cut off length of tape, thev two liftingheads 234 and 23T! move upwardly in unison a slight distance, stillmaintaining the vacuum at the head 244. While in this slightly elevatedposition, the cam 225 through the rocker 228 starts shifting the crosshead 225 to the left s'o as to bring the piece of tape into wipingcontact over a roller 265, Fig. 41, which roller is revolved within aglue pot 266.

The glue pot 266 is a more or less retangular vessel having a dependingleg 216 which extends down on the inside of the plate |34 to be attachedthereto by means of the screws 21|. The roller 265 is slotted to, ineffect, provide a plurality of rollers. Fingers 2`i2 secured to theinner side of the pot 26E extend across into the slots of the roller 285to have their upper sides substantially tangential to the periphery ofthe roller sothat as the hea-d carries the tape on across over theroller, the tape will not be permitted to adhere to the roller and bepulled away from the head, but will be stripped from the roller by meansof these fingers so that the under side of the tape becomes coated withglue which is carried up out of the pot on the periphery of the rollerand the tape remains pulled against the under side of the head to becarried on past the roller.

The glue applying roller 265 is mechanically driven by means of a chain213 passing around a sprocket on the shaft 68 and carried up around anupper sprocket 2l4, Fig. 44, on the end of a shaft 2li: which carries aworm 216, Fig. 43, meshed with the worm gear 2H carried on the end of alongitudinal shaft ZllS. This shaft 21'8 extends through a supportinghousing 219, Fig. 44, to have a spur gear 288 on its forward end meshingwith the spur gear 28! which is fixed on the i end of the shaft 282which carries the glue roller The glue roller 285 is thus constantlydriven from the shaft 65! whereby a fresh supply of glue is alwayscarried around the periphery of the roller ready to be contacted by thetape as it is carried thereover. The glue roller revolves to have itsupper side travel in the direction of and with a peripheral speed thesame as that of the movin r tape carried thereover.

From the glue roller, the head 244 carries the tape on over to the leftuntil the tape is immediately above the folded end of the blank 88 thenpositioned thereunder. When the head 244 reaches this left handposition, the cams 254 and fr, Eal then revolve to have their contoursdrop the heads 22s? and 243 so that the head 244 presses the tape intoposition on the folded end of the blank 88, the tape then being in thatposition as indicated in Fig. 47. For convenience this length of tapewill hereinafter be termed a wrapper, designated by the numeral 288. Itis to be noted that the wrapper 282 then adheres to that portion of theblank SS which lies between the first and second folds and projectslaterally from the blank by both ends.

The lifting head 23'? then lifts to open the port 239 and therebydestroy the vacuum at the head 244 so that the head releases the wrapper283. Following that operation, the lifting head 234 lifts the head 244from the wrapper and the head is carried to the right again to repeatthe entire operation above described.

As soon as the head 244 has lifted from the applied wrapper 283, theplate 18 advances the blank then carrying the wrapper on around to th-enext stopped position where the wrapper is to be folded by its ends downaround and under and back up against the blank 88. At this position,there is a wrapper folding mechanism as shown on an enlarged scale inFigs. 31-35. Referring to Figs. 31 and 32, the blank S8 with theadhering wrapper 283 on its top side is brought under the guide block284 and stopped at the position e. In this position, the blank 88 isstopped to have left edge immediately below the left hand corner of theblock 284 and the end of the wrapper 288 projects therebeyond. A finger285 is pivoted on the end of an arm 28E which is set in a block 282depending from the upper guide block 284. A foot 288 extends from thearm and carries a pin 28B which enters a slot in the recipi'ocable slide298 carried by tongues between the side blocks 29E and 292. The lowerend of the slide 299 carries a roller 298 which is maintained in rollingContact with the periphery of the cam 294 by means of a spring 295secured to the slide by one end and by its other end to the block 292.Cam 234 is fixed to the shaft 69 and its contour is so formed that theslide 222 is allowed to remain in a normal lowered position under theinfluence of the spring 285 so as to have the upper end of the finger285 then positioned as indicated in Fig. 32.

The slide retaining blocks 22E and 292 are secured to a cover plate 29Swhich in turn is fastened to a back plate 227 that is secured to theplate 24. The cover plate 296 is provided with an internal cut awayportion within which a bar 298 carrying a rack gear 298 and 88B on itsedges may reciprocate. A spring Bill secured to near the upper end ofthe bar 298 passes downwardly within the cover plate 228 to be attachedto its inside wall as a means of normally ret-aining the bar 22S in alowered position. The lower end of the cover plate 295 is slotted toafford an entrance into the interior opening or chamber within the plateand a T-shaped block Bilt. has its shank inserted through the Slot toabut against the bar 298 and is there secured by means of the screws 383to have a head ef the block in sliding contact with the outer face ofthe plate 29E. A roller 384 is carried in the lower end of the block 3D2and rides on the periphery of a cam 335 which is fixed on the shaft 52to the right of the cam 2&4.

A spur gear 88o meshes with the rack and in turn carries a largerdiameter gear i' on its left side which meshes with a smaller spur gear388 xed on a shaft 328 whi n entends through the cover plate 285 tocarry a folding li.

The initial operation in folding the wrapper 283 is that of the arm 285which is brought from the position as indicated in Fig. 32 around to theposition as shown in Fig. 3l to have the upper end of the linger thenpressing the folds of the end of the blank 88 snugly one against theother and upwardly against the wrapper all in compressive Contactagainst the under side of the block 284. This movement of the arm 285 isoccasioned by suitable rotation of the cam 224 to permit the roller 223to drop on down to a lowered portion of the periphery under the inluenceof the spring 295.

The folding finger Bill is shaped to have a flat under face terminatingat a heel Sli which is at the center of rotation of the finger and whichis mounted to be at the forward end of the block 284 immediately abovethe edge of the blank 88 then below the end of the wrapper The cams 224and 325 have the proper peripheral form such that the finger 3l 8 isrevolved first counterclockwise, Figs. 3l and 82, to cause the finger tocome around into contact with the projecting end of the wrapper 228 andbend it around therewith. As soon as the finger 3i@ has turned thewrapper 283 around under and started backwardly and upwardly to approachthe under side of the blank 88, the finger 225 is then rocked rearwardlyby means of the slide 2% being lifted so that as the nger 235 moves outfrom under the blank 88, the finger 3 l il may then continue its travelaround upwardly to bring the end of the wrapper 282 snugly against theunder side of the blank 88 as indicated in Fig. 32. As soon as thatposition is reached, the contour of the cam 3535 is such that the fingerBle is then reversed in travel to come back to its normal position asshown in Fig. 3l and the finger 235 remains in the rocked position asindicated in Fig. 32 until the next blank S3 is brought around for thewrapper folding operation.

Upon completion of the folding of the forward end of the wrapper aroundthe blank 88, the plate 'it is then given its next successive degree oftravel and brought to a standstill again to have the wrapper brought tothe position Fig. 3l, wherein the blank S3 is stopped to have its rearedge aligned with the rear end of a block i so Ias to permit thetrailing end of the wrapper 283 to extend freely therebehind. A secondtucker ringer 5&3 is carried in the manner of the finger 285 but cn theforward side of the slide 2% to have a pin Sill engaged within a slot inthe slide so that when the slide 293 is allowed to drop under theinfluence of the spring 295 by suitable rotation of the cam 2M, thefinger 3l 3 is brought from its normal position as indicated in Fig. 32around to have its upper end wipe over the under folded end ofthewrapper 2st and then stop so as to retain the blank 88 incomp-ressive contact with the under side of the block 3l2.

Another foiding iinger 3l5 is rockably carried to extend normallyupwardly and rearwardly from the rear corner of the block Big to have aheel at the center of rotation of the nger immediately at the rear lowercorner of the block 3m. This finger SI5 is mounted on a shaft 3l@ whichextends through the cover plate 296 to carry therebehind -a spur gear 3l 'l which is meshed with a larger gear tit secured to a third gear Siewhich is meshed with the rack its as best illustrated in Fig. 32, thearrangement of the gearing between the nger and the rack being exactlythe same as that for the finger l.

Following the initial movement of the linger Siti, the earn 5?@5 thenpushes upwardly on the bar to cause rotation of the folding finger 3l 5downwardly and around toward the under side of the blank i, followingthe initial travel of which, by the time the rear wrapper end has beencarried around the edge of the blank 88, the cam lieti has then revolvedsuioiently to raise the slide 29e -again and thus rock the ringer 3i3back to its normal position as indicated in Fig. 32 so that the ringer355 can travel on around to its nal terminal position to complete thefold as indicated in Fig. 32. The cam 385 then has the proper peripheryto permit the rack gear to follow and return the ringer 395 to itsnormal position as indicated in Fig. 3l. In describing the operationsincident to the folding of the wrapper 233 about the end of the band283, it is to be understood that first the forward end of the wrapper isfolded in one station e and then the blank 88 is advanced to the stationf where the rear end of the wrapper is folded. However these operationsoccur simultaneously on different blanks et, there being a blank atVeach position when the operations take place.

The plate 'iii is then given its next degree of travel whereupon theblank with its wrapper then carried therearound and sealed on the blankas indicated in Figs. 49, 5G, and 5l, is shifted to the next station fora final operation of applying some identification mark to the wrappedblank. In the present instance, I employ an embossing device, generallydesignated by the numeral 32u, see Figs. 36, 37, 33, and 29, which ismounted on the inside of theV plate ld at the position where the wrappedblank 33 stops. In this position, theV blank t8 is between an upper xeddie 32l which is supported from the body 322 and a lower movable die 323which is mounted on a slide 324 guided by the body to extend inwardlytherefrom to carry a roller 325 which rides on the periphery of the cam326. The slide 32e is normally held in the lowered or inner position bymeans of a spring 327 secured by one end to the slide and the other endto the body. Any suitable characters or marking may be, of course,provided in the dies 32E and 323 but in any7 event, when the blank 88comes to rest therebetween, the cam 325 revolves to press the slide 32dupwardly to force the lower die 323 against the under side ofthe wrapper283 to emboss therein in cooperation with the other die B2i, themarkings, herein shown as the letters (3. K, Fig. e9. The cam 32@continues to revolve with the shaft Se and thus permits the spring 327to lower the slide 32@ and remove the die 323 so as to release the blank38.

Thereupon the plate i8 is given its next degree of rotation to againstop. In this position, all operations on the blank 88 have beencompleted and all that remains to be done is to release the blank fromthe retainer nger This is accomplished by a mechanism for lifting theringer 83 so that the blank may drop from the needles 8l and fall fromthe machineready for use. 'Ihe mechanism for releasing the blank willnow be described.

On the shaft i is fixed a cam 323, see Fig. 1, over which passes an arm329 having its rear end carried by the bracket 253. The arm ridesby asuitable bearing against the cam 32S, such bearing being the saine asthat shown for the arms 252 and 26B. The forward end of the arrn 329 isnormally pulled downwardly by means of the spring 33B attached to thetable top 56.

Through a link 33E, the fo-rward end of the arm S529 is connected to theforward end of the lever 332 which in turn is iixed toa shaft 333carried by the standards 33t and 335, the shaft 333 extendingtransversely therebetween. Near the standard 335, a spur gear 335 isfixed to the shaft 333 to mesh with another spur gear 331 carriedthereabove, see Fig. 3, and slightly behind on a stub shaft whichextends through the upper end of the standard 335 to have a level` 333fixed on the right hand end of this shaft to hang normally downward.Extending from the right side of the lever 338 is a pin 339. When theshaft 64 carries the cani 323 around to the properposition, the arm 32Sis allowed to lower, whereupon the lever S38 is swung forwardly by itslower end and the pin 839 is brought-sharply up against the then rearside ofthe retainer nger 83 to knock it open. By reason of this sharpimpact, the inertia of the blank and its attached wrapper 2&3 issufficient to permit the needles Sl' to be withdrawn from the blank sothat the blank thereupon falls from the finger to the iloor or into anysuitable receiving receptacle (not shown).

While the mechanism has thus far been described as applying to a singleblank e3 and the sequence of operations followed through as applying tothat single blank, it is to be understood of course, that a single blank38 is placed Linder each finger Sii as the plate i3 revolves from oneposition to the next so that while one operation is being conducted,other, operations are being performed on the other blanks as well, allin the sequence as above indicated. In summary, I have provided amechanism which essentiallygrips a blank and never releases that blankuntil the iinal operation has been completed. The gripped blank is movedfrom one position to the other for succeeding operations. First one endis folded and then a second fold is performed on that end with meansbeing provided to form sharp definite lines of folding. A wrapper is cutfrom a strip of paper, glue is applied to one side of the wrapper, andthen the wrapper is set down on the folded end of the blank.l First oneend of the wrapper is folded around the blank and then the other end bymechanism simulating the operation of the fingers of ones hand. A finaloperation, if preferred, is provided for in that an identifying mark maybe applied by suitable means to the wrapper. Finally the blank thusfolded and wrapped and marked, is released from the original 'grippingmeans Without further operations being required on it.

In further reference to the blank folding operations above described, itis to be noted that the fold lines ab and cd o-f the blank 98 areproperly located by widths of the fold plates |58 and |93, as indicatedby comparison of Figs. 22 and 25, the first folder having its plate |58longer and the fing-er |59 nearer the mounting plate |34 and thecorresponding second fold plate 93 and its folding finger |9I.

The method of guiding the blank from one operating position to anotheris easily traced in Figs. 52-59. Beginning with the initial receivingposition ef the blank at the finger E33, Fig. 52, the blank 88 isstarted cn its circumferential travel around the periphery of the plate|34 to have the blank enter under the lower out-turned end of the guide55 and over a metal floor 349. The blank 88 travels therebetween untilas above indicated, the plate l comes to a stop to have the blank thenpositioned by its outer free end over the anvil i5?, Fig. 22, under theplate |58. In fact in the form herein shown, the plate |58 is integralwith the guide |55 and is in eect a portion of the guide |55 reduced intransverse length by having a notch cut out of the guide |55, Fig. 53,the notch being immediately above the folding block |59.

The folding block H59 comes up and wraps the free end of the blank overthe inner or right hand end of the plate |58. As indicated in Fig. 54,the block |59 returns slightly from its extreme folding position andthere remains a time interval while the blank 88 is being shifted onaround circumferentially. While the block E59 thus remains in thatposition, the fold of the blank 98 is so retained that as the blankprogresses, the fold comes under the upturned lip 34| of a guide band342 which is spaced from the iioor 349 a sufiicient distance to permitthe folded end of the blank to travel therebetween. Of course after theblank 88 has entered under the lip 34|, the block |59 may then and doesturn on back to its position within the recess in the anvil |57.

In approaching the second folding mechanism |15, the guide 342 is cutaway on its forward right hand corner over the anvil |92 to leave theplate portion |93 to the left thereof. The finger |94 is normallypositioned as indicated in Fig. 29 within this notched portion of theguide 342 so that as the folded end of the blank comes within this cutaway portion, the fold passes under the linger |94 and although freefrom retaining inluence of the guide 342, the ringer retains the foldedover end of the blank firmly against the blank itself. It is in thisposition that the folding block |9| then comes over the end of the blankto form the second fold therein by turning the blank end over the plate|93. The block |9| remains for a time interval in a slightly elevatedposition from its extreme folding position while the blank 88 is beingthen moved to its next position and at least for a sumcient timeinterval to permit the folded end of the blank to enter under the lip343 of the guide 344 so that as the blank then continues moving, thefolds are retained in their compressed positions.

In reference to the head 244 which is employed to transfer the wrapperband 283 to the folded blank, I employ a flexible arm 345 fixed to thebar 223, Figs. l and 6, to be spaced therefrom to have its lower endturned around horizontally to be initially at the end of the guide 344over a block 345 which is fixed to the plate ilil at the position wherethe blank 88 stops to receive the wrapper band 283. Thus as the foldedend of the blank 83 emerges from the forward end of the guide 344, thatfolded end passes up onto the top side of the block 345 and under theend of the arm 345, Fig. 58. Then when the head 244 descends to depositthe wrapper 233 on the blank 88, a portion of the head 244 comes downagainst the arm 345 and springs it back out of the way to permit theapplication of the wrapper band. Then as the head 244 lifts, the arm 345springs back into position over the blank to maintain the foldedcondition.

The next movement of the blank 88 slides the blankalong under the arm345 to carry the blank and its attached band under the block 284 toenter under the inclined portion 34? thereof so that continued movementof the blank tends to bring the band downwardly with greater pressureagainst the folded end of the blank. The blank then continues on to thestop position at e, Fig. 3l, where the initial band fold is completed.

From that position e, the blank is carried on over to the position fwithout any guide means between those two positions. From the positionj, the folded and wrapped end of the blank passes on through the groove348 in the block 3|2 and then without further guidance between the diesin the embossing device 320 from which the blank end emerges to be freefrom further guiding influences.

While I have herein shown and described my invention in the form as nowbest known to me, it is obvious that structural changes may be madewithout departing from the spirit of the invention, and I, therefore, donot desire to be limited to that precise form beyond the limitations asmay be imposed by the following claims.

I claim:
